Reducing Latency of DAG-based Consensus in the Asynchronous Setting via the UTXO Model. (arXiv:2307.15269v1 [cs.DC])

DAG-based consensus has attracted significant interest due to its high
throughput in asynchronous network settings. However, existing protocols such
as DAG-rider (Keidar et al., PODC 2021) and ``Narwhal and Tusk'' (Danezis et
al., Eurosys 2022) face two undesired practical issues: (1) high transaction
latency and (2) high cost to verify transaction outcomes.

To address (1), this work introduces a novel commit rule based on the Unspent
Transaction Output (UTXO) Data Model, which allows a node to predict the
transaction results …
